Design Space Explorer issue

I'm using Quartus II 14.1 64b and DSE II launched from Quartus gui. Running on Centos 7 Linux.

When I try to run DSE (for a seed sweep) from its gui, I get the following error

Traceback (most recent call last):

File "<string>", line 22, in <module>

File "explorer.py", line 1379, in main

File "explorer.py", line 1286, in main_impl

File "explorer.py", line 346, in run

AttributeError: 'Explorer' object has no attribute 'server_url'

Design Space Explorer finished

Found info that says DSE II wants to use a local server but I'm at a loss as to what I need to do to get the tool to run. DSE II seems to be quite new and documentation is a bit sparse.

Any thoughts/help would be appreciated.
